JCoins Voucher Errors

In my logs I see:

Use of undefined constant MODULE_JCOINS_VOUCHER - assumed 'MODULE_JCOINS_VOUCHER' (this will throw an Error in a future version of PHP)

I think it is tied to the fact that I cannot enable jCoin vouchers here:

And this it is not actually activated in the system.

I may be wrong of course, but can you help? This is a new install of jCoins vouchers on WotLab Suite 5.3.x Thanks in advance!

RE-installed, still errors

We figured out what the issue was and it was actually unrelated to installation. I characterize my error as PEBCAC: Problem exists between computer and chair. I'm saving some pride and shall not divulge the stupidity. THANK YOU.
